The cm-fx6 module has an on-board AW-NH387 WiFi/BT module which is based on Marvell's SD8787 chip and is connected to the usdhc1 controller. Unfortunately, the chip gets unresponsive if the Bluetooth AMP (Alternate Mac/Phy) function gets probed but the loaded firmware doesn't support it. For instance, this is the case for the most recent firmware in linux-firmware (Version 14.66.35.p52). Thus, just add the required nodes but leave the usdhc1 node disabled explicitly. Users who disabled the Bluetooth (AMP) support of their OS can then conveniently enable WiFi (or even plain Bluetooth) support with a simple device tree overlay/bootloader configuration.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
